Prepareing for 3L swap

[SHOgoFast]

I am going crosseyed from all the reading and have decided to just ask a few questions.

At this point the turbo will remain on the car. That is why I elected FI for this post. There was a really good post a few days ago about sources for turbo goodies and I have visited a lot of the sites. With that being said how far will the t28 take me on the 3L. I am not opposed to upgradeing to a larger turbo but really do not want to spend 700-1000 to do so. Anyone selling a t3/t04 or similar sized turbo? Secondly, the turbos i have looked at have different flanges than the ADC turbo I currently have. What is the best way to get compatability, new flanges welded on?

I will be port matching the 3L heads for use with 2.5 intake components. Is it adviseable to do so with the heads attached to the block? Again, if I can save ~160 for new head gaskets and head studs/ bolts I would like to. I know it can be done, but if suggestions to do them with the heads remove prevail I will go with the wisdom of CEG.

Gonna tack on one more quick one as the folks that will most likly reply to this will know this answer too. Everyone suggests putting in new Clevite 77 rod bearings when installing the 3l, what about the mains with the block out in the open, do those too?

As always, if some of this should be easy for me to find I will be happy with links or search suggestions. I think my reg date/post count/vehicle development indicates that I do far more reading the BS posting.

Thank you everyone.

OK where can I start here

1) T28 will not work period don't waste your time it is sized for 2.5 smaller.

2) you need to strip the kit down and switch to a 4 bolt and cut the 5 bolt off it is worthless and hard to bolt up.

3) The intercooler you have will support 350 whp max if even that .

4) turbo can be had for 600.00 new and you need to get a T3/T4 60 trim or 61mm wheel for max flow.

5) change the rod bearings but low mileage motor leave the mains alone unless you want to change all cradle bolts they are good still.

6) convert heads with the heads on just remove the cams and blow out the shaving once you are done be sure to cover all openings.

7) look into to a stage 3 clutch for the increase torque

8)the inlet flange on the intercooler must be change to a 2" from the smaller t28 one

9) Or I can show you how to convert a xs intercooler for $300-400 buck labor and parts good for 800 hp

10) You need to buy a 80mm MAF

11)You need at least 42 lb injectors

12) new tune

13) And last warmonger to fine tune it

all this to convert the 3 liter the kit you have is not going to support more than 325whp if you are lucky.

Or just buy the disco potato turbo spend the money and change nothing you might get 325whp with stock 3 liter same piping too. which is a tricked out T3

Looks like the limits of the T-28 is about 300 whp.

I too would replace both sets of bearings for the peace of mind.

Thanks for all the input, I greatly appreciate it.

1. t28 out the window

2. You are referring to the downpipe correct?

3. was worried about that

4. any particular vendor you or others prefer?

5. I will change the rod bearins, but most likly leave the mains alone, mileage will be less than 25k.

6. glad to hear that, didnt want to pull heads unless i had to.

7. that was already in the plan, however i did not mention it.

8/9. If I can find the cash to do the above mentioned changes and new turbo this will be my most likely route.

10. Does it matter what injector size the MAF is calibrated for I have found various ones from 24lbs to 42lbs.

11. Any better source for 42lbs injectors other than ebay?

12/13. Warmonger will be my tuner.

You said "...all this to convert the 3 liter the kit you have is not going to support more than 325whp if you are lucky." Do you mean staying with the t28 and small intercooler, or even with the larger turbo and intercooler the piping will STILL limit me to 325?

Thanks again!!!

Jim, I hear you on going to peace of mind route. What is the common bearing that is spun on the Duratecs? Rod or Main?

[beyondloadedSE]

rod bearings

no 325whp if you just put on the disco potato with your same setup. If you are satisfied with that output of approximate 400 hp just buy that turbo with the largest turbine housing you can put.

the turbo will flow 36 lb/min and on a stock 3.0 liter will net that power but If I was you I would ask if you can change the turbine outlet so you can move the powerband up top more.

Dicso Potato is way over priced. Look for a GT30 series turbo on eBay, and go from there.

So I have been on a quest for a larger turbo to support the 3L and some 42lb injectors. Now, finding the right sized turbo is easy, finding it for a price I can swallow is not. Burrita, you mentioned I should be able to get a new turbo for around 600.00...can you guide me to that source please.

The injectors are a different story all together. I can only seem to find return style injectors in that size and I will be needing returnless style. Im looking to you on this one Stazi as you are the only turbo 3L I know of with returnless.

At least 90mm lightning MAFs are all over the place.

as for the turbo i got mine for around 800 a bit higher than 600 so i cant help there, but as for the injectors call BILL J at team ford. he can find you some for a good deal, and he can either get you a set of injectors or a set of matched injectors.
